Description

Technical Field

[0001] The present application relates to the field of wire embedding devices, and in particular to a wire embedding device for a micro motor stator. Background Art

[0002] During the motor production process, enameled wire needs to be inserted into the stator slots or rotor slots of the motor to form the stator winding or rotor winding of the motor. The existing wire insertion method still relies mainly on manual operation. For larger motors, wire insertion is relatively easy; however, for smaller motors, especially the stator windings of small motors, since the stator core is a slender cylinder, it is difficult for people to reach into the cylinder to operate, which brings a lot of inconvenience to the wire insertion operation and seriously affects production efficiency. During the wire insertion process, the enameled wire is also not easy to straighten and straighten. If you are not careful, the enameled wire may become tangled, or the edge of the core may scratch the enameled wire coating, causing a local short circuit in the motor and affecting product quality. Summary of the Invention

[0003] In order to facilitate the wire embedding operation of the stator of a micro motor, the present application provides a wire embedding device for the stator of a micro motor.

[0004] The present application provides a micro motor stator wire embedding device, which adopts the following technical solution: A wire embedding device for a micro motor stator includes a frame, a clamping seat for clamping the stator, a fixing post, a guide post, and a guide assembly, wherein the clamping seat is arranged on the frame, the fixing post is arranged on the frame, one end of the enameled wire is arranged on the fixing post, the guide post is arranged on the frame, and the guide assembly is arranged on the guide post. The guide assembly is used to wind the enameled wire into the wire embedding groove of the stator.

[0005] By adopting the above technical solution, the fixing column is used to fix one end of the embedded wire, and the embedded wire is wound into the wire embedding groove of the stator through the guiding component. The cooperation between the fixing column and the guide column makes the wire embedding route more stable, reducing the damage of the enameled wire caused by shaking due to manual operation.

[0006] Optionally, the guide assembly includes a reciprocating screw, a guide motor, a guide block, a matching block, a guide wheel for guiding the enameled wire, and a matching piece. The length direction of the reciprocating screw is parallel to the axial direction of the stator on the clamping seat. The reciprocating screw is rotatably connected to the guide column. The guide motor is used to drive the reciprocating screw to rotate. The guide block is threadedly connected to the reciprocating screw. The matching block is slidably connected to the guide block in the horizontal direction. The guide wheel is rotatably connected to the matching block. The matching piece is used to drive the matching block to move in the horizontal direction.

[0007] By adopting the above technical solution, the guide motor and the reciprocating screw realize the reciprocating motion of the guide wheel, forming a movement similar to manual winding, controlling the distribution of the embedded wire on the stator axis, and improving the uniformity of the embedded wire. The guide wheel is rotatably connected to the matching block, which can reduce the friction during the winding of the enameled wire and avoid scratches on the paint. The matching block is moved in the horizontal direction through the matching parts to form a complete winding action.

[0008] Optionally, the mating part includes a mating spring and a mating column, and a sliding groove is provided on the side wall of the guide column toward the mating block, and the sliding groove is a parallelogram, and the sliding groove includes two vertical grooves and two parallel inclined grooves, a vertical groove and an inclined groove form a groove group, and the angle between the vertical groove and the inclined groove is greater than 90°, and the groove depth gradually increases from one end of the vertical groove away from the inclined groove to the end of the inclined groove away from the vertical groove, and the mating column is slidably connected to the mating block, and the mating spring is used for the mating column to abut against the bottom of the vertical groove or the inclined groove.

[0009] By adopting the above technical solution, the sliding groove limits the movement direction of the mating block. Through the sliding of the guide block and the sliding of the mating block, the mating column is located in the sliding groove. When the mating column moves from one slot group to another slot group under the action of the spring, the mating column cannot return to the previous slot group due to the slot depth, so that the path for the mating column to guide the mating block is unique, thereby improving the rationality of the stator wire winding.

[0010] Optionally, a lead plate is provided on the guide column, and a guide hole is opened on the lead plate for guiding the enameled wire to the guide wheel.

[0011] By adopting the above technical solution, the guide hole provides a fixed guide path for the enameled wire, preventing the enameled wire from getting tangled due to loosening or shaking before entering the guide wheel; the lead plate can straighten the enameled wire in advance, reduce friction with other components, and reduce the risk of paint damage.

[0012] Optionally, the guide column is slidably connected to the frame in a direction approaching or moving away from the fixed column, and a cooperative component is provided on the guide column, and the cooperative component includes a first bevel gear, a second bevel gear, a rotating wheel, a pull rope and a retraction member, the first bevel gear is provided on one end of the reciprocating screw rod, the second bevel gear is rotatably connected to the guide column, the second bevel gear is meshed with the first bevel gear, the rotating wheel is provided on the second bevel gear, one end of the pull rope is wound around the rotating wheel, and the other end of the pull rope is provided on the frame, and the retraction member is used to move the guide column close to the fixed column when the enameled wire is wound into the wire embedding groove.

[0013] By adopting the above technical solution, when the guide assembly guides the enameled wire for winding, the reciprocating screw drives the first bevel gear to rotate, the first bevel gear drives the rotor to rotate, the pull rope is wound onto the rotor, and the distance from one end of the rotor to the rotor is shortened, that is, the guide column moves in the direction away from the corresponding winding stator wire embedding groove. As the guide column moves, the enameled wire can be evenly wound into the wire embedding groove, reducing the stacking of the enameled wire and improving the winding effect of the enameled wire. When one wire embedding groove in the stator is completed, the guide column can be moved close to the fixed column again through the retraction member to allow the next wire embedding groove to be wound.

[0014] Optionally, a rotating column is provided on the second bevel gear, the rotating column is coaxially arranged with the second bevel gear, one end of the rotating column is provided on the second bevel gear, the rotating wheel is rotatably connected to the rotating column, and a plurality of guide bars are provided circumferentially of the rotating column, and a plurality of guide grooves are opened on the inner side wall of the rotating wheel, and the guide grooves are used for the guide bars to cooperate with the return member, and the return member includes a mounting magnet, a first magnet, a second magnet and a return spring, the mounting magnet is arranged on the side wall of the rotating wheel, and the first magnet and the second magnet are distributed along the moving direction of the guide column. When the enameled wire is wound to a state that fills the wire embedding groove, the mounting magnet and the first magnet are in an oppositely attracted state, so that the guide bar disengages from the guide groove, and the return spring is used for the guide column to move in a direction close to the fixed column, and to make the mounting magnet and the second magnet in a like-charge repulsive state, so that the guide bar is clamped in the guide groove again.

[0015] By adopting the above technical solution, when the wire embedding groove is filled with enameled wire, the mounting magnet is aligned with the first magnet, and the first magnet attracts the mounting magnet, causing the guide bar to detach from the guide groove. At this time, the roller can rotate relative to the rotating column, and the pull rope cannot generate tension. Under the action of the retraction spring, the guide column is driven to move in the direction close to the fixed column until the second magnet is aligned with the mounting magnet, and the second magnet repels the mounting magnet, causing the guide bar to enter the guide groove again. At this time, the roller rotates with the rotating column again, so that the guide column can be moved away from the fixed column when the enameled wire is wound next time, and the moving direction of the guide column is perpendicular to the attraction direction of the magnet, which facilitates the detachment of the mounting magnet from the first magnet and the second magnet.

[0016] Optionally, the guide bar is provided with a guide slope for facilitating entry into the guide groove.

[0017] By adopting the above technical solution, the guiding bevel reduces the resistance when the guide strip and the guide groove are engaged, so that the guide column can be smoothly reset after retreating, thereby improving the smoothness of the mechanism operation, reducing mechanical failures, and ensuring the continuity of the wire embedding process.

[0018] Optionally, a plurality of spring plates are circumferentially provided on the clamping seat, and the spring plates are used to abut against the outer side wall of the stator.

[0019] By adopting the above technical solution, the elasticity of the spring sheet abuts against the outer wall of the stator, providing a stable clamping force, so that the axis of the stator is parallel to the moving direction of the guide block, thereby improving the winding effect of the enameled wire. The elastic clamping avoids hard squeezing and damage to the stator core, protects the stator structure, and improves the product qualification rate.

[0020] Optionally, a clamping groove is provided on the upper end surface of the clamping seat, and the clamping groove is used to limit the rotation of the stator.

[0021] By adopting the above technical solution, the clamping slot cooperates with the stator structure to further fix the circumferential position of the stator, prevent the enameled wire from being misplaced due to the rotation of the stator during wire embedding, ensure that the wire embedding is strictly distributed according to the preset slot position, avoid wire embedding confusion caused by stator offset, and improve winding consistency.

[0022] Optionally, the clamping seat is rotatably connected to the frame, and the frame is provided with a positioning piece for positioning the clamping seat, the positioning piece includes a positioning spring and a positioning bead, and the clamping seat is provided with a plurality of positioning grooves, and the plurality of positioning grooves correspond to the number of wire embedding grooves of the stator, and the positioning bead is slidably connected to the frame, and the positioning spring is used for the positioning bead to be clamped in the positioning groove.

[0023] By adopting the above technical solution, when one wire embedding slot in the stator is completed with winding, the staff can rotate the clamping seat so that the positioning bead enters the adjacent positioning slot. Since the clamping slot on the clamping seat is clamped with the stator, the next limit slot can be accurately aligned with the guide assembly, which is convenient for the staff to operate and reduces the occurrence of enameled wire winding errors due to angle deviation.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The guide assembly is used to wind the enameled wire into the stator's wire slot; 2. The cooperative component is used to move the guide column away from the fixed column so that the enameled wire can cover the entire wire embedding groove during the winding process; 3. The clamping seat is used to fix the stator so that the axis of the stator is parallel to the sliding direction of the guide block. BRIEF DESCRIPTION OF THE DRAWINGS
